Abstract

APARELHO ELETRÔNICO E ACESSÓRIO. A presente invenção refere-se a suprimir a interferência causada por uma mudança em outro sinal com um sinal de comunicação. Como meio de solução, um aparelho eletrônico (100) tem uma pluralidade de contatos alinhados e eletricamente conectáveis a um acessório (200). A pluralidade de contatos inclui primeiro e segundo contatos de sinal (TC12, TC13) usados para transmitir um primeiro sinal como um sinal de dados e um segundo sinal como um sinal de relógio em uma comunicação entre um aparelho eletrônico e um acessório, um terceiro contato de sinal (TC14) usado para transmitir um terceiro sinal, e um quarto contato de sinal (TC11) usado para transmitir um quarto sinal. O terceiro e o quarto sinal são sinais cujos níveis de sinal não mudam durante a comunicação do primeiro e do segundo sinal. O primeiro e o segundo contato de sinal são dispostos adjacentes um ao outro, e o terceiro contato de sinal está disposto em um dos dois lados do primeiro e do segundo contato de sinal, e o quarto contato de sinal está disposto no outro.
